Protect Your Transmission with BD Diesel

The BD Diesel Thermostat Bypass is a critical upgrade for 2019-2024 Ram 6.7L trucks equipped with 68RFE or Aisin AS69RC transmissions. Factory cooler bypass valves are known to jam in the recirculation mode, which prevents fluid from reaching the cooler and leads to dangerous transmission temperatures. This bypass kit eliminates that failure-prone valve, ensuring your transmission fluid is always flowing through the cooler for maximum thermal protection.

Key Benefits of the Cooler Bypass

• Prevents Overheating: Keeps transmission fluid circulating through the cooler at all times.
• Eliminates Failure Points: Removes the stock bypass valve that is prone to jamming.
• Engineered for Reliability: Designed specifically for the high-demand 6.7L Cummins platform.
• Easy Installation: Includes everything needed for a direct-fit installation.

BD Diesel has been a pioneer in diesel performance since 1989, and this bypass kit is a testament to their engineering excellence. By ensuring consistent cooling, you can extend the lifespan of your transmission and maintain performance even under heavy towing or high-load conditions. Don't let a faulty factory valve cause premature transmission failure; upgrade your cooling system today. For the best selection of performance diesel parts, shop the full catalog at GGCRACING.
